Enji Todoroki (Endeavor): The patriarch of the family and the former No. 2 (now No. 1) Pro Hero. Possessing the "Hellflame" quirk, his intense obsession with surpassing All Might led him to be abusive and neglectful, though he later seeks redemption. Rei Todoroki: Enji’s wife, who possesses a powerful ice quirk. The severe stress and abuse from Enji led to a psychological breakdown, resulting in her being hospitalized for years after she accidentally burned Shoto. Toya Todoroki (Dabi): The eldest son. He inherited a fire quirk even hotter than Endeavor's but a body resistant to ice, leading to severe burns. Believed dead for years, he became the villain Dabi, driven by a deep desire for revenge against his father. Fuyumi Todoroki: The eldest daughter and a schoolteacher. She possesses an ice quirk and acts as the family peacemaker, desperately wishing for her broken family to heal and move past their traumatic history. Natsuo Todoroki: The second son and a college student. He possesses an ice quirk and holds the deepest, most vocal resentment toward Endeavor, finding it incredibly difficult to forgive his father for past abuse and Toya's perceived death. Shoto Todoroki: The youngest son and one of the main protagonists of the series. He possesses the perfect hybrid quirk, "Half-Cold Half-Hot." Initially fueled by a hatred for his father, Shoto learns to accept his fire powers as his own and strives to become a hero on his own terms.
